Full technical detail▾
Overview
A SSRF vulnerability exists, bypassing existing controls on the software. This can allow a user to request internal services for a full read SSRF, returning any data from the internal network.
the application is using a whitelist, but the whitelist can be bypassed with @ and encoded value of @ (%40) GET /proxy/?url=http://development.demo.geonode.org%40geoserver:8080/geoserver/web This will trick the application that the first host is a whitelisted address, but the browser will use @ or %40 as a credential to the host geoserver on port 8080, this will return the data to that host on the response.
Affected packages
geonode >= 3.2.0, < 4.1.3.post1
Remediation
Upgrade to a patched release:
geonode 4.1.3.post1
